Moreover the stifl ness of the fastening button for the most' part makessuch a fastening device useless.

'The object of the present invention is to prostrap shoe, in which duoean adjusting device in a the fastening button,-slmilarly to'a buttonthat is stitched on, can be adjusted so as to move in all directions ina longitudinally slotted eyelet, The latter is provided with transverse,semi-circular pressed out portions, which serve to fix the button in thedesi-red position, and thus give the adjusting device suclr a flatstructure that by 10- eating the same tinguished from an ordinary shoe.

The subject matter of the invention is illustrated .in the accompanyingdrawing. Figure 1 showing the eyelet part section, V j

Figure 6 a longitudinal section along the 6-6 of-Fig.5. In Fig. 1 a isan eyelet consisting of sheet metal, celluloid or the like material,which, as'is clear from Fig. 2, has anarrow longitudinal slot b. Thisslot b has at regular intervals several widened aperturesd. At each ofthese apertures d the eyelet-plate a groove. On the underside pftheeyelet plate a leaf spring e is secured at] so as tobear firmly againsta. This eyelet plate a is stitched into between the upper and the liningI the strap shoe provided therewith cannot be disin longitudinal line ispressed up to form a the shoe leather, as shown by Figs. 4, 5 and 6. Atthe end of the strap i is provided-as usual the fastening buttonconsisting of a semi-circular shoe button.

The device operatesas fol1ows:--,

' In fastening the button the cross bar h of the button 9 is turned inthe longitudinal direction parallel to the slot b in the eyelet part aand inserted therein. In this position the button can be displaced inthe slot b. When the strap has been adjusted to the .desired length, bycrossh at one of the widened turning the cross bar apertures d in theeyelet part, the button is held in this position. 1 In the first placebecause the bridge piece m is wider in the transverse position than theslot b in the eyelet part a and secondly because the cross bar It ispressed through the agency of the leaf spring e into one of thegroove-like depressions c, the fastening device is flat in form, so'thatwhen the sameis stitched between the upperand lining of the shoe, .the
